Lester Holt was supposed to be an unbiased moderator, holding the candidates to account during a fierce first US presidential debate.
But Donald Trump supporters are up in arms at what they claim was favourable treatment of Hillary Clinton by the NBC anchor, who hosts America's most-watched nightly news show.
No matter who you want to win, a fair and balanced hearing for both nominees is clearly in the interests of democracy and robust debate.
While Holt brought up a list of Trump's weaknesses and scandals, he barely mentioned Clinton's email embarrassment, the Benghazi attack or her perceived untrustworthiness. The Republican candidate raised her Trans-Pacific Partnership flip-flop on his own.
Here is every moment Holt weighed in on:
ON TAXES AND EMAILS
"Mr Trump, we're talking about the burden that Americans have to pay, yet you have not released your tax returns," said Holt.
"Don't Americans have a right to know if there are any conflicts of interest?"
When Trump said he would release his tax returns after an audit, Holt pointed out that he could do so right now.
Trump: "Almost every lawyer says, you don't release your returns until the audit's complete. When the audit's complete, I'll do it. But I would go against them if she releases her emails."
Holt: "So it's negotiable?"
Trump: "It's not negotiable, no. Let her release the emails. Why did she delete 33,000..."
Holt: "Well, I'll let her answer that."
When Clinton didn't answer the question in her reply, Holt pushed her this far: "He [Trump] also raised the issue of your emails. Do you want to respond to that?"
Lester Holt questions all attacks on Trump which put him on defense all night!! Not 1 question on any things she has done #debates— Mike Matusow (@themouthmatusow) 27 September 2016
Nearly all of Holt's followups and fact-checking efforts were directed at Trump, not Clinton. Look for a big debate over his role— HowardKurtz (@HowardKurtz) 27 September 2016
Lester Holt train of thought right now:
Tax returns- ck
Birth Cert- ck
Emails? Health? Benghazi?— Eric Bolling (@ericbolling) 27 September 2016

Bad job by Lester Holt & mainstream reporters on Trump walkout. Let him hang himself, tying the noose isn't your job. Ethics, assholes.— Tony Maglio (@TonyMaglio) 27 September 2016
ON RACIAL DIVIDES
When Trump talked about the importance of "law and order" in healing America's racial divide, Holt interjected that stop-and-frisk had been ruled unconstitutional and that it had been called "a form of racial profiling".
He did then ask Clinton if she believed the police were "implicitly biased against black people", but quickly turned back to Trump to quiz him on the Barack Obama "birther" conspiracy.
"For five years, you perpetuated a false claim that the nation's first black president was not a natural-born citizen," said Holt.
"You questioned his legitimacy. In the last couple of weeks, you acknowledged what most Americans have accepted for years: The President was born in the United States. Can you tell us what took you so long?"
And he pressed the (admittedly important) point: "I just want to get the answer here. The birth certificate was produced in 2011. You've continued to tell the story and question the President's legitimacy in 2012, '13, '14, '15..."
And again: "We're talking about racial healing in this segment. What do you say to Americans, people of colour..."
Lester Holt has done a fine job as moderator. Not too intrusive, moving this along, fact-checking when necessary. #debates— Nicholas Kristof (@NickKristof) 27 September 2016
Since we were all so poised to jump on Lester Holt, let us say: He did a good job.— Josh Greenman (@joshgreenman) 27 September 2016
ON IRAQ WAR
Holt then entered an argument with Trump over whether he supported the Iraq War - the businessman claims he was an early opponent, although his comments at the time were rather ambiguous and he gave lukewarm support for the invasion in 2002.
Meanwhile, Clinton supported the war.
"Why is your judgment any different than Mrs Clinton's judgment?" asked Holt.
ON CLINTON'S APPEARANCE
The moderator quizzed Trump on an insult towards Clinton.
"Earlier this month, you said she doesn't have, quote, 'a presidential look'. She's standing here right now. What did you mean by that?" he asked.
Holt received mixed reviews from social media and the global press, much of it based on that person or publication's political leanings.
Twitter dubbed Holt the invisible man, asking where he had gone and why he wasn't moderating.

Right-wing daily The Washington Times gave Holt an "F" grade, saying he was "anything but moderate", giving Trump "the most pointed questions all night" and not questioning the Democratic nominee on the Clinton Foundation pay-for-play allegations, or FBI investigation into her emails.
TVLine noted that Holt's questions on race and birtherism might lead Trump supporters to accuse him of pro-Clinton bias. "But voting records prove Holt is a registered Republican, so it's not as if he's a diehard liberal. Bottom line: Moderating this debate was a thankless job, but Holt performed admirably under considerable fire."
Slate praised Holt for asking "good, tough, smart questions" while Fortune said Holt "saved his fact-checking for a few, spare moments in the debate, and he mostly focused on Trump's statements."
Fox News host Megyn Kelly said Holt did a "fine job" and conservative radio host and Trump supporter Hugh Hewitt praised the moderator for giving Trump "plenty of time" to answer questions.
But former New York Mayor Rudy Giuliani criticised Holt for getting involved in a stop-and-frisk debate he knew nothing about and not interfering on Trump's behalf.
The Republican nominee himself had a perhaps surprising view.
"I thought Lester Holt did a great job," said Trump. "I thought the questions were very fair."
